Abstract

A semi-continuous process for producing a polymer water-in-oil emulsion which comprises: (a) combining: (i) an aqueous solution comprising at least one water-soluble monomer and (ii) a mixture comprising a hydrophobic liquid, a hydrophobic monomer and an oil-soluble surfactant; (b) homogenizing the mixture from (a) to form a water-in-oil emulsion; (c) deoxygenating said homogenized water-in-oil emulsion; (d) continually adding the homogenized water-in-oil emulsion to a reactor while adding a deoxygenated initiator solution; (e) heating the mixture from (d) under polymerization a conditions so as to form a polymer water-in-oil and (f) recovering a polymer water-in-oil emulsion.
